Translate the sentence into an inequality.
The sum of a number times 10 and 19 is at least 21.
Use the variable x for the unknown number.
10 x + 19 ≥ 21
The sentence "The sum of a number times 10 and 19 is at least 21" can be translated into the inequality:
10x + 19 ≥ 21
where x represents the unknown number.
To translate the sentence into an inequality, we can start by breaking down the sentence into different parts.
First, "The sum of a number times 10 and 19" can be translated as:
(x * 10 + 19)
Next, "is at least 21" implies that the expression should be greater than or equal to 21.
Combining these parts, we get the following inequality:
x * 10 + 19 ≥ 21
This is the translation of the given sentence into an inequality using the variable x for the unknown number.
